# EffectCraft — the desktop app (`effectcraft`) and the CLI/MCP server (`effectcraft-cli`), built from this
|

# repository:
|
||||
#
|
||||
# nix build # → ./result/bin/effectcraft, ./result/bin/effectcraft-cli
|
||||
#
|
||||
# Kept in step with the release workflow (.github/workflows/release.yml) and packaging/:
|
||||
# * `Cargo.lock` drives the dependencies (`cargoLock`), so there is no vendorHash to bump. The
|
||||
# git sources (storytold/craft-libs, storytold/filmcraft) are fetched at the revision the lock file pins;
|
||||
# * the desktop file, hicolor icons, MIME types and AppStream metadata are the same files the
|
||||
# .deb/.rpm ship (packaging/linux/), so `apt` and NixOS users see one identical EffectCraft;
|
||||
# * `doCheck` is off: the test suite needs corpora and a GPU the Nix sandbox cannot provide
|
||||
# (`cargo xtask ci` is the gate). `pkgs.effectcraft.overrideAttrs { doCheck = true; }` runs it.
|
||||
#
|
||||
# Everything in the product is pure Rust, so this needs no build system beyond cargo plus the
|
||||
# libraries winit/wgpu `dlopen` at run time (see `runtimeLibs`).
|
||||
#
|
||||
# Desktop sessions: the window opens natively on Wayland (GNOME/Mutter, Hyprland and other
|
||||
# wlroots-style compositors) and falls back to X11/XWayland. File dialogs go through
|
||||
# xdg-desktop-portal, so the session needs a portal backend: GNOME ships one
|
||||
# (`xdg-desktop-portal-gnome`); on Hyprland enable
|
||||
# xdg.portal = { enable = true; extraPortals = [ pkgs.xdg-desktop-portal-gtk ]; };
